SHOE-F 1 153,139. Specification of Letters Patent. No Drawing. IApplication filed December 29, 1914. Serial No. 879,611.

7 '0 all whom it may concern:

Be it known that I, HARRY SNELL, a citizen of the United States, and aresident of Hanover, in the county of Plymouth and State ofMassachusetts, have invented an Improvement in Shoe-Fllers, of which thefollowing description is a specification.

This invention relates to a new composition of matter. While thecomposition may be used for various purposes and in different relations,I primarily intend it for use as a shoe filler that is to be applied tothe shoe to fill the cavity of the inner sole level with the welt,thereby to place it in condition for receiving the outer sole.

An important ob3ect of my invention is to provide a shoe filler thatwill not crack, and

which is flexible, waterproof and sets quickly.

In carrying out my invention, the ingredicuts or certain of them areheated and. the composition is preferably applied to the shoe in aheated condition. The shoe filler embodying my invention preferablycontains cork or like substance, certain adhesive matter and awaterproof substance. Said cork or like substance constitutes a base offinely divided material or a finely divided base material. The corkshould be applied in granular form, and it is rendered waterproof byincorporating therewith some suitable waterproofing material, which-isin itself flexible after it has been incorporated as an ingredient ofthe composition. For this purpose, I preferably employ a vulcanized orsulfur chloridized oil,- preferably a vegetable oil, and with or withoutother admixture." Such oil is a waterproofing liquid or fluent materialwhich is thick and tough but flexible and which sets quickly. I havefound in practice that such material does not only not crack or becomebrittle in itself, but when incorporated with the cork and otheringredients of the compo sition retain such qualities. The corkpreferably in a comminuted condition is rendered thoroughly waterproofby the application of the said oil or admixture thereto, with which itbecomes thoroughly impregnated. With the waterproofing material, Ipreferably add a suitable amount of rosin, which not only acts as anadhesive or binder, but also adds to the waterproofing qualities of thecomposition. With the said ingredients, I also preferably employ asuitable quantity of a material possessing strong adhesive condition itremains sticky for a lengthy period of time. While I may employ theforegoing ingredients in any desired proportion, I preferably use thefollowing proportions: cork 2 lbs., rosin 1 1b., castor-oil andgum-resin 1 1b., vulcanized or sulfur chloridized oil 1 gill.

In preparing the composition I melt the rosin and the castor-oil andgum-resin, addmg thereto the vulcanized oil, preferably in a heatedcondition, and when the compositlon 1s soft and of a water-likeconsistency, I

add the cork in granular condition.

The composition is allowed to harden, being preferably molded into theshape of loaves and is heated for application to the shoe. A shoe fillerconstructed as above described will not burn, nor will it crack, andin,manufacturing the same, I am enabled to make a saving in cementitiousmaterial. Not only isthe composition thoroughly water: proof, but itsets quickly, and remains flexible throughout the life of the shoe.Moreover when a sole of a shoe is removed for repair, the shoe fillerwill retain its proper position in the shoe, thereby facilitating therepairing of the latter Having thus described one embodiment of. myinvention and the best mode known by me for carrying the'same intoeffect, I desire f it to be understood that although specific terms areemployed, they are used in a generic and .descriptive sense and not forpurposes of limitation, the scope of the invention being set forth inthe following claims.

Claims:

1. A shoe filler or like composition, comprising comminuted cork-likematerial, rosin, vulcanized oil and castor-oil and gum-resin.

2. A shoe filler or like composition comprising cork, rosin, vulcanizedoil and castor-oil and gum-resin in substantially the followingproportions, namely, cork 2 lbs, rosin 1 1b., castor-oil and gum-resin 11b., and vulcanized oil 1 gill.

8. A shoe filler or like composition comprising a base of finely dividedmaterial, rosin, vulcanized oil and castor oil and gumresin insubstantially the following proportions, namely, finely divided basematerial 2 pounds, rosin 1 pound, castor oil and gum and vulcanized oilin substantially the following proportions, namely, finely divided basematerial 2 pounds, rosin 1 pound, and 15 vulcanized oil 1 gill.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing Witnesses.

HARRY SNELL.
